basically everything in the upper left quadrant of this diagram would be 
viable from an abundance point of view

i think the colour of the ersatz-chlorophyll would not only depend on 
the metal itself, but also what exactly the surrounding molecule is 
doing .. but i do not know enough about organic chemistry to make 
predictions






Beatrice Otter:



But the thing is, what is abundant on one planet may or may not be abundant elsewhere. We already know that Earth has a lot of phosphorous compared to other planets, for example. Earth may not be a good example, and even if it is, any other planet we settle might be odd.
